I have in the past ran a primary on an old 133amd with 64mb of ram with a
secondary made from a salvaged sparc2 running 25 different domain names and
not a single glitch or slow down, right now I have 147 domain names on a
PII 400 with 128mb of ram pumping out 200Kbps all day and the uptime is 243
days with out incident or problem (my caching server is a P200 pro running
dnscache), so I would say you should be fine forever and then some with
your planned config, but hey if you have the bread why not. Overkill is
good in most cases!!

I just ordered a copy of v3.0, and I am looking forward to playing with
it at home. My first project is a master and slave DNS server.

Literature I have read gives me the impression that for a single domain,
a simple PC will do. In this case two, one for master, one for slave.
My home connection is dual T1, and I have other Linux and Windows
machines running. My plan is to grab a pair of PII 300 machines on the
cheap, 256MB of RAM on each, ~8-10 GB 7200 RPM IDE drive plus a cheap
video card (Matrox G200/G400 comes to mind) and run OpenBSD on both with
BIND, SSH and ipchains (or whatever firewall runs on OpenBSD). SSH
server will be used primarily for remote access via a Windows or Linux
client.

Is this enough? Overkill I do not mind, would prefer the Ethernet
connection (100BASET) and Internet connection (3Mbps up/3 Mbps down) to
limit performance rather than PC hardware. Any suggestions or comments
would be most welcome.
